Biomechanical forefoot varus has an effect on cycling power outputDinsdale, NL., Williams, AG. Can Forefoot Varus Wedges Enhance Anaerobic Cycling Performance in untrained Males with Forefoot Varus? Institute for Performance Research – original scientific paper.
A degree of caution should be taken when interpreting the results of this small study which is none the less interesting food for thought and may leave the reader with more questions than answers; e.g. the definition of forefoot varus vs. forefoot supinatus and the potential implications of not defining this.
However, the results from a cohort of 6 subjects concluded that there is a strong correlation between power output and forefoot varus deformity with anaerobic cycling and that forefoot varus wedges may improve short term power output in these individuals. Worth reading and pondering.
